arms @3 and 44 are suitably offset to the left at the lines 43' andMrespectively.

Since the side closure 35 is connected continuously with the coverthroughout the entirerange of movement of the latter, the side closureis moved positively with the movement of the cover.

Moreover, since the meansconnectingthe cover with the side closureoperates smoothly'without any clashing of parts, the cover is easilymovable between its open and closed positions. Such smooth and easyoperation of the cover is highly V desirable in a machine of the classherein described. f

Although I have herein shown'and described my invention in terms of aparticular embodiwithout departure from the scope of my-invention, whichI undertake to express accordingto;

the following claims.

I claim: 1 1. In a, cabinet of the class described: the combination of apair of separate closuresmounted on said cabinet for movement alongdifferentlydirected paths between open and closed positions and havingparallel motion components in their movements into open position and-intheir movesure causing said closures to open and close with one another.

5. In a cabinet'for' a phonograph: the combi nation of a pair ofseparate, pivoted closures on said cabinet having their pivot axesparallel but spaced from one another, said closures beinghu adapted toswing in the same angular directions 7 1 in'their movem'ents into openand closed positions; respectively; members respectively secured to saidclosures and in adjacent relationship with one another; anda' slidingpivoted connection between said members causing said closures to openand close each with the opening and closing of the other."
